PostgreSQL is available in all Debian versions by default. However, the stable versions of Debians "snapshot" a specific version of PostgreSQL that is then supported throughout the lifetime of that Debian version. The PostgreSQL project also maintains an apt repository with all supported of PostgreSQL available.
Should packages not be available for your distribution, or there are issues with your package manager, there are graphical installers available.
Finally, most Linux systems make it easy to build from source.
Debian includes PostgreSQL by default. To install PostgreSQL on Debian, use the apt-get (or other apt-driving) command:
apt-get install postgresql-9.1
The repository contains many different packages including third party addons. The most command and important packages are (substitute the version number as required):
If the version included in your version of Debian is not the one you want, you can use the PostgreSQL Apt Repository. This repository will integrate with your normal systems and patch management, and provide automatic updates for all supported versions of PostgreSQL throughout the support lifetime of PostgreSQL.
To use the apt repository, follow these steps:
deb http://apt.postgresql.org/pub/repos/apt/ YOUR_DEBIAN_VERSION_HERE-pgdg main
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | \
sudo apt-key add -
sudo apt-get update
For more information about the apt repository, including answers to frequent questions, please see the apt page on the wiki.
Newer versions of PostgreSQL for older versions of Debians are available in Debian backports. For information on how to enable and use the backports repository, please see the backports instructions page at Debian.
Once backports is enabled, you can install PostgreSQL the same way as with the builtin repositories.
Installers are available for 32 and 64 bit Linux distributions and include PostgreSQL, pgAdmin and the StackBuilder utility for installation of additional packages. The PostgreSQL 8.4 installers have been tested with a number of Linux distributions and should work on Ubuntu 6.06 and above, Fedora 6 and above, CentOS/RedHat Enterprise Linux 4 and above and others. The 9.0 and later installers have only been tested on more recent distributions.
Download the installer from EnterpriseDB for all supported versions.
Note: The installers do not integrate with platform-specific packaging systems.
